2 claims. orage-68) l This invention relates to a method of packagingobjects to prevent rusting as well as the package in Which the object isplaced.

In order that a clearer understanding of the invention may be had it maybe explained that certain automotive and machine parts and othermetallic objects are commonly shipped in lpaper containers in the natureof a bag or envelope-on which can be printed the description of theobject with directions for its installation and/or use, the makers nameand other desired information. It is likewise common to-treat theseparts or objects alone `@before packing with rust-resisting solutioncontaining grease or oil. In practice it has been found that on arrivalat a distant destination or after storage for a period of time, thissolution or oil coating, where the object or part has been in contactwith the container, has been absorbed by the paper and that at suchplaces of contact oxidation or rusting occurs Which, in the case ofautomotive parts such as piston rings and other objects machined to ahigh tolerance, rendered them useless as not being capable ofinstallation or interohangeability in the position or for the purposeintended.

The practice of using oiled or greased paper for such containers andinserting therein by hand the parts or objects after they had beentreated or dipped in a rust-resisting solution has also provedunsatisfactory in that oxidation or rusting develops at the points ofcontact on the object by the fingers of the person handling and packingthem.

Therefore, one of the principal objects orf my invention is to providean improved method and means whereby such metallic objects can beinserted into convenient paper containers and thereafter dipped into andremoved from a rustresisting solution so as to (1) effectually coat theobject with such solution without handling; (2)

simultaneously coat the paper of the container with such solutionsuliiciently to ensure that the. points of contact in the interior ofsaid container shall not absorb or withdraw from the coated object therust-resisting solution so applied to its surfaces; and (3) drain awayupon removal of the package tfrom the solution all surplus thereof whichif left in the paper container would cause it to burst in packing or torot in shipping or storage.

A further object of my invention is .to provide convenient means forsuspending the paper packages or containers in the process of dippinginto the rust-restisting solution and/or after removal therefrom so asto ensure such drainage.

' y@ther objects will" be in part obvious fromv the annexed 'drawing`and in part hereinafter indicated in connection therewith by thefollowing analysis of thelinvention.'A

Thisvinventi'onlaccordingly consists in the features'oi" construction,combination of parts and in the unique relationof theV members and intherelative proportioning'anddisposition thereof,4 all as more completelyoutlined herein.

To enable others skilledA in the-art tolfully comprehend theunderlying'ieatures of this invention,

that-they may embodythe samevloy thenumer-l ousmodicationsin structureand4 relation contemplated by the invention',l a drawing depicting oneform ont the invention has'ibeen annexed as part of this disclosure, andin such drawing like characters 4of reference denote corresponding partsthroughout all of the views, in which Fig. 1 shows a rear elevation of asingle compartment envelope container with the cover flap up or open;

Fig. 2 is a rear elevation of a multiple compartment envelope;

Fig. 3 is a front elevation of the three compartment envelope containerillustrated in Figure 2 with the top iiap closed and the Whole foldedior shipment. The wording is merely illustrative;

Fig. 4 is a semi-diagrammatic elevational view showing how the packageis suspended to drain.

Referring rst to Fig. 1 there is shown a single compartment envelope 5with the ilap 6 up and showing segments 'l and 8 cut away at each of thebottom corners to form orifices for the entry into and drainage out ofthe container of the rust-resisting solution. For suspension of thecontainer a perforation l0 is provided which is cut through the top flap6 in a position ofi-center to allow proper drainage through saidoriiices when the container is suspended in an inclined verticalposition by means of a hook or projection I l passed through theperforation I0 as shown in Fig. 4, perforation I0 can be suitably edgedor reinforced for heavy objects as indicated at l2.

In' Fig. 2 there is shown a multiple compartment container seperated bythe paper of the front and back of the container or envelope which partsare glued, sewed, or otherwise fastened together between each,compartment as indicated by the dotted lines I3. The orifices or cutout segments at each bottom corner of each compartment are indicated at1'. In this figure there are three perforations I0 in the top flap forsuspension, these being placed in such a position 01T- center o'f eachcompartment, when the envelope or container is folded horizontally theseperfora- The quality and strength of the paper employed depends on thesize and weight of the metallic object and the nature of the solution,and by cutting away'segments 1 of both bottom corners of the containerthere is provided means for the entry of the solution in the process ofdipping and for drainage thereafter. To suspend the con- Y tainerpackaging the metallic object I4 indicated by dotted lines in Fig. 4 forthe purposes of. dipping in the rust-resisting solution I5 and/orY ofsuspending the container thereafter in vertical position to permitdrainage of the surplus solution, the circular or other suitably shapedhole I0 in the top flap or cover provides a simple and inexpensive meanswhereby the container can be hung or suspended alone or with othercontainers of a similar design on the same or similar hooks, rods, orprojectie While my invention and the mode of practising it have beendescribed and exemplified in certain specific forms or manners, it willbe obvious that the principles herein disclosed may be varied orembodied in different forms or manners from those described Withoutdeparting from the spirit of the invention defined in the followingclaims.

What is claimed is:

1. A flexible container for dipping into a liquid while containing anarticle for treatment by the liquid, the container comprising a,substantially rectangular at envelope and having one end opensubstantially throughout the length thereof, a substantially rectangularflap extending the length of the envelope'from the open end of theenvelope, an off-center perforation in said ap adjacent one of the uppercorners, and the bottom of said envelope having a diagonally oppositecorner cut away to perforate the pocket of the envelope thereby topermit drainage when the container i-s removed from the treating liquid.

2. A flexible container for dipping into a liquid while containing anarticle for treatment by the liquid, the container comprising asubstantially rectangular envelope transversely elongated to severaltimes its length and having one end open substantially4 throughout thelength thereof, the envelope having spaced vertical lines of connectiondividing the envelope into pockets of equal dimensions adapted to befolded along said lines of connection, a substantially rectangular flapextending the length of the envelope from the open end of the latter,said folded lines traversing said ap, perforations in said flap, atleast two of said perforations being olf-center on opposite sides of oneof the fold lines, said elongated envelope being cut away at the bottomfrom each corner to provide openings in the bottom corners of eachpocket to perforate the latter therebyto permit drainage when thecontainer is removed from the treating liquid.
